Senna Leaf Tea Information

The ancient Egyptian doctors used senna over 3500 years ago for their royal patients and the elite. It was also used by the Arabian physicians as far back 9th century A.D. After being introduced to Europe during the Crusades, its popularity as an herbal remedy exploded. While available as single product, senna is often combined with a variety of aromatic herbs.

Today senna is a commonly used laxative and is found as an active ingredient in products such as Senokot, Fletcher's Castoria, and Ex-Lax Gentle Nature. Senna can be found growing naturally in most tropical regions of the world. Both its leaves and its seeds are medicinal. Senna is able to relieve constipation by stimulating the colon, whereby speeding along the passage of the contents. Consequently, there is less time for fluid to be absorbed from the stool and it remains soft.
